BACKGROUND OF INVENTION

The present invention is directed to novel methods for administering compositions containing essential fatty acids for use by pregnant and/or lactating women to optimize infant neurological development, length of gestation, and birth weight and to provide improved nutritional support for women prior to, during and after lactation. Further, the invention is also directed to methods for prevention and treatment of essential fatty acid deficiencies and conditions related or derived therefrom.

Essential fatty acids (EFAs) are important for all humans in general and women specifically. Failure to ingest the appropriate amount of essential fats daily may result in improper digestion, which in turn may cause inadequate absorption of other nutritional factors, including vitamins and minerals.

Additionally, the body derives its energy from triglycerides, a molecule of glycerol with three fatty acids attached. Stored fatty acids support bodily functions, and are especially important when individuals are between meals or must go without food. Furthermore, the body cannot produce all the necessary fatty acids it requires. An example of such is both linolenic and linoleic acids. Thus a failure in the intake of the proper amount of EFAs can have wide ranging negative implications. Furthermore, insufficient daily intake of EFAs can lead to various levels of failure in a woman's reproductive system.

For this reason, it is especially important in the case of women who are pregnant or breast feeding or plan to become pregnant or plan to breast feed that methods of nutritional supplementation of dietary compositions containing EFAs be developed.

All major fatty acid classes were altered in the pregnant state. Of these differences in polymorphonuclear leukocytes, oleic acid and αa-linolenic acid have been shown to significantly increase (13 and 26%, respectively) and stearic acid and arachidonic acid (AA) has been shown to significantly decrease (8 and 30%, respectively). This may suggest that attenuated PMN function in pregnancy may originate from a reduction in the available pool of cellular fatty acids. Furthermore, this reduction arises as a direct result of a pregnancy-induced shift in circulating fatty acids from polyunsaturated to monounsaturated forms. Clin Diagn Lab Immunol. 1999 July; 6 (4): 587-593. These shifts in circulating EFAs, have been implicated in low birth weight, shorten gestation and in the occurrence of birth defects.

Due to a new born infant's high growth rate and nutritionally dependent state upon the mother, EFAs in the mother's diet continue to be important after birth especially if the mother is to breast feed.

At some time prior to the end of pregnancy, pregnant women face the decision of whether or not to breast-feed their infants. It is estimated that over 50% of all mothers choose to breast-feed their infants. See The Merck Manual, 185:1929-1931 (16th ed. 1992).

Furthermore, the number of women deciding to breast-feed appears to be on the increase, particularly in higher socioeconomic groups. Id. Most experts would agree that this increase is very desirable in view of the numerous recognized nutritional benefits for developing infants which accompany their consumption of human milk. Because of the nutritional benefits for infants, many health care providers and dietitians believe breast-feeding is sufficiently important to warrant that every effort be made to breast-feed, even if only for a short time. See Whitney et al., Understanding Nutrition, 493-504 (6th ed. 1993).

Moreover, in addition to the nutritional benefits of breast-feeding, many women simply want to breast-feed their infants for emotional or psychological reasons. However, regardless of a woman's underlying reasons for breast-feeding, her nutritional status is implicated in the decision of whether to breast-feed her child. For example, a nutritional deficiency in a woman may severely limit the quantity of breast milk which is produced or, in some cases, entirely prevent lactation from occurring.

Generally speaking, the nutritional benefits of breast-feeding stem from the unique nutrient composition and protective factors present in breast milk which promote infant health and development. Id. at 494. For example, breast milk generally contains all of the vitamins required for infant development, with the possible exception of vitamin D. Id. at 500. Further, breast milk is an abundant source of minerals and, more importantly, some minerals are present in breast milk in highly desirable ratios (e.g., the 2-to-1 ratio of calcium to phosphorus in breast milk is ideal for the absorption of calcium). Id. Breast milk also contains invaluable immunological agents, including antiviral agents such as immunoglobulins, and antibacterial agents such as lactoferrin.

In addition to the above discussed vitamins, minerals and immunological agents, breast milk also contains various “energy nutrients.” For example, breast milk contains lactose which is the carbohydrate present in breast milk and which facilitates calcium absorption. Id. A relatively small amount of protein, primarily in the form of alpha-lactalbumin, is also present in breast milk, thus placing less stress on the infant's immature kidneys. Id. Breast milk additionally contains fat along with fat-digesting enzymes. Id. Linoleic acid, a fatty acid, is found in large quantities in breast milk. Id.

The presence of EFAs in breast milk is significant for various reasons, as described below. Because the body derives most of its energy from stored triglycerides, and the body cannot make all the EFAs it requires, for example linoleic acid or linolenic acid, these indispensable EFAs must be supplied through the infant's food. Again, EFAs are important for the developing brain, immunological system and cardiovascular system, and have some role to play in every organ of the body. Linoleic acid is the most important member of the omega-6 family of fatty acids. The body uses linoleic acid to synthesize an important carbon fatty acid, arachidonic acid, which helps maintain the structural integrity of cell membranes.

Linolenic acid is the most important member of the omega-3 family of fatty acids. The body requires this fatty acid to make eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Many body tissues require EPA and DHA. DHA is especially important in the retina and in the cerebral cortex of the brain. Half of the DHA in a fetus's body accumulates in the brain before birth, and half after birth, an indication of the importance of fatty acids to the fetus during pregnancy and then to the young infant during lactation.

Successful breast-feeding requires that the mother maintain good nutrition and adequate rest. A good, nutritional diet is needed to support the stamina that nursing an infant requires. Beyond this, however, a woman must consume a nutrient-rich diet to produce nutrient-rich milk.

A healthy nursing mother generally makes about 25 ounces of milk each day. To produce this milk, the mother needs to consume 650 kcalories above what she would normally require for herself. Woman are advised to eat about 500 kcalories worth of extra food and let the extra fat left over from pregnancy provide the rest. Women may not consume enough food for many reasons, including the desire to lose all of the weight gained during pregnancy. But restricting food and energy in this fashion will result in breast milk which is lacking in nutrients, low quantities of breast milk or, in the worse case scenario, no breast milk at all.

According to the medical literature, a nursing mother should eat foods high in nutrients and drink plenty of fluid. Nutritional deprivation in the mother generally reduces the quantity, more so than the quality, of the milk. So while—woman can produce milk with sufficient protein, carbohydrate, fat and minerals even if their own intake is insufficient, the quality of the breast milk is maintained at the expense of the mother's own nutrient repositories. Moreover, quantities of particular vitamins, such as B6, B12, A and D, in breast milk will actually decline in response to an inadequate intakes by the mother.

Infants have different nutritional needs than those of children and adults. They require more fat and less protein than adults. Breast milk contains high concentrations of fat-digesting enzymes that allow for highly efficient fat absorption. Breast milk, as well as colostrum, contains the essential fatty acid linoleic acid. Understanding Nutrition, Whitney and Rolfe, 6th Ed., 136-40 (1993).

Full term babies who are not fed enough linoleic acid suffer from dermatosis and growth failure. These conditions are easily reversed when linoleic acid is added to the infant's diet. Fatty acid deficiency in a breast-feeding infant is a hazard of long term low fat parental dieting. The Merck Manual, 16th Ed., 968 (1992).

Methods of administering linolenic acid to lactating females have been previously described. Specifically, Horrobin, U.S. Pat. No. 5,264,217, discloses methods for increasing the total fat content of milk, the essential fatty acid content of milk and the flow of milk during lactation, or for preventing or reducing the normal decrease in milk fat content that occurs during prolonged lactation, by administering gamma linolenic acid, dihomo-gamma-linolenic acid or their mixture to a lactating female.

Other references disclose compositions and methods that have been developed for achieving fat enrichment of ruminant milk for consumption by humans. In general, animal feed is supplemented with fatty acids. In turn, the milk produced by the ruminants is itself rich in fatty acids.

Chalupa et al., U.S. Pat. No. 5,004,728, describe a method for increasing milk yields in lactating ruminants. The ruminants are fed somatotropin and salts of long chain fatty acids. The fatty acid in the feed increases the level of long chain fatty acids in the milk produced by the ruminant. One long chain fatty acid suitable for this inventive subject matter is linoleic acid.

Nishimura et al., U.S. Pat. No. 5,635,198, describe a granular agent comprised by an active core coated by certain fatty acids and oils to be administered to ruminants. This granular agent has a superior absorption rate and results in, among other benefits, efficient lactation in the ruminant.

Scott et al., U.S. Pat. No. 3,925,560, describes a feed supplement for ruminants comprising fatty acids encapsulated with a protein-aldehyde reaction product. These fatty acid supplements, including linoleic acid, provide high energy feed supplements for ruminants. These supplements will result in the ruminate producing a milk very high in unsaturated fats.

Palmquist et al., U.S. Pat. No. 4,642,317, describe a process for feeding ruminants fatty acids in the form of their calcium salts, which are added to feed. This process would allow dairy cows to make milk high in fats, without depleting their own fatty acid stores.

Richardson, U.S. Pat. No. 5,143,737, describes a method for the modification of ruminant food so that the ruminant will produce milk with modified fat. This method comprises a non-toxic food to be surrounded by an acid-sensitive nontoxic cross linking material. Animals eating this composition will make milk with a higher level of unsaturated fats.

However, none of the above formulations provide women with essential fatty acids in amounts and proportions necessary to optimize infant neurological development. Further, the prenatal nutritional supplements containing vitamins and minerals are entirely lacking in essential fatty acids. In the case of the enriched ruminant milk, while this milk may be a good source of fatty acids for adults, ruminant milk is not recommended for infants because even supplemented formula cannot match the immunological benefits of breast milk.

Therefore, there remains a need for a nutritional formulation which optimizes infant neurological development. It is also desirable to have nutritional formulations which prevent a woman's stores of fatty acids from becoming depleted during lactation. There is also a particular need for nutritional formulation which provides essential fatty acids in optimal ratios and amounts, along with required vitamins and minerals. Moreover, it is desirable to have formulations and methods which prepare a woman's body for the stresses imposed by lactation.

SUMMARY OF INVENTION

The methods of the present inventive subject matter for administering compositions containing essential fatty acids for use by pregnant and/or lactating women overcome the deficiencies of currently available methods.

In one embodiment of the inventive subject matter, a method for administering essential fatty acids comprises administering a composition of essential fatty acids to a pregnant or lactating woman, wherein at least two of the essential fatty acids are selected from the group consisting of linolenic acid, linoleic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, an omega-3 fatty acid, an omega-6 fatty acid and mixtures thereof; wherein the essential fatty acids in the composition are present in an amount ranging from about 100 mg to about 1,000 mg per 55 kg of body weight of the pregnant or lactating woman; and wherein the essential fatty acids maximize the weight of a member selected from the group consisting of an embryo, a fetus or a multiple gestation.

In another embodiment of the inventive subject matter, a method “for administering essential fatty acids comprises administering a composition of essential fatty acids to the pregnant or lactating woman, wherein at least two of the essential fatty acids are selected from the group consisting of linolenic acid, linoleic acid, arachidonic acid, eicosapentaenoic acid, docsahexaenoic acid, an omega-3 fatty acid, an omega-6 fatty acid, and mixtures thereof; wherein the essential fatty acids in the composition are present in an amount ranging from about 100 mg to about 1,000 mg per 55 kg of body weight of the pregnant or lactating woman; and wherein the essential fatty acids optimize the length of gestation of a member selected from the group consisting of an embryo, a fetus or a multiple gestation.

In yet another embodiment of the inventive subject matter, a method for administering essential fatty acids comprises administering a composition of essential fatty acids to a woman, wherein at least two of the essential fatty acids are selected from the group consisting of linolenic acid, linoleic acid, arachidonic acid, eicosapentaenoic acid, docsahexacnoic acid, an omega-3 fatty acid, an omega-6 fatty acid, and mixtures thereof; wherein the essential fatty acids in the composition are present in an amount ranging from about 100 mg to about 1,000 mg per 55 kg of body weight of the woman; and wherein the essential fatty acids treat essential fatty acid deficiencies in the woman.

DETAILED DESCRIPTION

As used herein, “nutritional stores” refers to the levels of vitamins, minerals and other nutrients which will be available for use by the mother, developing embryo, fetus and newborn infant.

“Nutritional status” refers to the presence or absence of any nutrient deficiency, or in other words, the extent to which physiological nutrient demands are being satisfied such that deficiency is avoided.

“Optimize neurological development” refers to attainment of the highest degree of neurological development possible through natural processes without the use of any unnatural substances or procedures, such as drugs, surgery and the like.

“Biologically active substance” refers to any substance or substances comprising a drug, active therapeutic substance, metabolite, medicament, vitamin, or mineral, any substance used for treatment, prevention, diagnosis, cure or mitigation of disease or illness, any substance which affects anatomical structure or physiological function, or any substance which alters the impact of external influences on an animal, or metabolite thereof, and as used herein, encompasses the terms “active substance,” “therapeutic substance,” “agent,” “active agent,” “active therapeutic agent,” “drug,” “medication,” “medicine,” “medicant,” and other such similar terms.

“Specific physiological needs” refers to the unique requirements for certain levels of certain nutrients by one class of persons, such as lactating women, pregnant women, etc., as distinguished from other classes.

“Biologically-acceptable” refers to being safe for human consumption.

“Neonate” refers to the offspring of a female mammal that is nursed by said female mammal and has not yet been weaned.

“Essential fatty acids” or EFAs may refer to any fatty acid that may be utilized by the body, and included, without limitation, chemical chains of carbon, hydrogen, and oxygen atoms that are part of a fat (lipid), are a major component of triglycerides, which may be classified as either saturated, polyunsaturated, or monounsaturated, and may be found in nature or produced synthetically. They may include without limitation cholesterol, prostaglandins, lecithin, choline, inositol, conjugated linolenic acid, myristic acid, palmitic acid, stearic acid, oleic acid, alpha-linolenic acid, eicosapentaenoic acid, docosapentaenoic acid, docosahexanoic acid, linolenic acid, gamma-linolenic acid, linoleic acid, omega 3 fatty acids, omega 6 fatty acids, omega 9 fatty acids, polyunsaturated fatty acids, long-chained polyunsaturated fatty acids, arachidonic acid, monounsaturated fatty acids, precursors of fatty acids, and derivatives of fatty acids.

The compositions and methods of the present inventive subject matter provide several specific new and unexpected benefits. First, the formulations may improve the nutritional status of a woman prior to conception. Second, the formulations may increase fetal birth weight. Third, the formulations and methods may increase the length of gestation. Fourth, the formulations ensure that both the mother and her infant or infants are provided with adequate energy during the period of lactation. Fifth, the formulations allow the mother to maintain adequate fatty acid stores for both her own use and for incorporation into her breast milk as her supplies are depleted during lactation. Sixth, the fatty acids optimize the overall development and neurological development of the infant consuming the breast milk. Fourthly, when administered prior to lactation, the present compositions prepare women for the increased physiological demands and stresses to be placed upon their bodies. Finally, the present compositions help women recover from pregnancy and lactation and prepare women for additional pregnancies and subsequent lactation.

Thus, the inventive subject matter provides for methods and compositions designed to be administered to a woman prior to the onset of pregnancy for the purpose of improving nutritional status prior to conception; methods and compositions designed to be administered during pregnancy to provide adequate nutrition for the pregnant woman and the developing embryo, embryos, fetus or fetuses; methods and compositions for administration during pregnancy to provide adequate nutrition to the pregnant woman and the developing embryo, embryos, fetus or fetuses for the purpose of increasing or maximizing the length of gestation and/or increasing or maximizing birth weight; and methods and compositions for the purpose of both enriching the woman's breast milk for the benefit of the child or children and also to directly benefit the woman. In fact, in some cases, the formulations may allow a woman to breast-feed her infant where, in the absence of taking the present composition, breast-feeding would have been either unsafe or outright impossible. Infants undergoing gestation while the mother's diet is modified according to the methods and compositions of the present invention, as described herein, may undergo advantageous in utero development and increase gestational duration. Furthermore, infants consuming the enriched breast milk, as described herein, will experience optimal neurological development. Further still, the present methods and compositions will help a post-partum woman to recover from her pregnancy and labor quickly and efficiently by providing her with the fatty acids lost in pregnancy and lactation. In addition, the present methods and compositions will place a woman in optimal condition for an additional pregnancy and the lactation that will follow by helping her increase her nutritional stores of critical nutritional compounds.

The present inventive subject matter is based, in part, on the discovery that when compositions having certain fatty acids, in certain amounts and proportions to one another, are administered to women prior to and during pregnancy and prior to and during lactation, embryos and fetuses in utero contemporaneously with said administration may experience increase in birth weight and length of gestation, as well as maximized development and that infants who consume the breast milk of said women will achieve optimized neurological development. In particular, supplementing the mother's diet with certain fatty acids for a period beginning at least ten weeks after conception, preferably at least ten weeks prior to conception and continuing through out the pregnancy and lactation period, and either ending when lactation ceases or being continued as a supplement will not only optimize the neural development of the breast-feeding infant, but also ensure that the mother has adequate essential fatty acids for her own use. The fatty acid supplement may also further contain vitamins and minerals to confer added health benefits to the infant or infants and mother. In addition to benefiting a developing human embryo or fetus, as well as a breast-feeding human infant, the present invention can also benefit the embryo, fetus and/or spring of non-human mammals wherein the mother mammal's diet is supplemented according to the methods and compositions of the present invention before, during or after pregnancy and said offspring are nursed by their mothers. The methods and compositions of the present invention could be administered to a mammal in animal feed, pill form, or other appropriate dosage forms to such mammals without limitation.

Without being limited by theory, the present compositions maintain and stabilize fatty acid levels in the blood before, during and after pregnancy and lactation. Maintenance and stabilization of fatty acid levels in the blood may serve beneficially in numerous bodily functions of both the mother and the embryo or fetus, such as, for example immunological development, immunoregulation and immunoresponse, production and maintenance of appropriate levels of various hormones beneficial to pregnancy, birth and lactation, such as for example, prostaglandin. Prostaglandin may serve to increase the duration of gestation. Additionally, maintenance and stabilization of EFA levels in the pregnant mother serves to maximize the development of the embryo or fetus neurologically and physically. Further, maintenance of fatty acid levels in the body of the mother may stimulate the production of breast milk which is enriched with the EFAs in amounts which optimize infant neurological development. These methods and compositions achieve such benefit to both woman who is planning to conceive or is pregnant and the enrichment of the breast milk through one or more natural biological pathways. For example, the arachidonic acid cascade may play a significant role in the enrichment of the breast milk Specifically, in the arachidonic acid cascade, linoleic acid is converted first to gamma-linolenic acid and then to further metabolites such as dihomo-gamma-linolenic acid and arachidonic acid which are precursors of 1 and 2 series prostaglandin respectively, as shown in the outline below:

The present composition contains at least two fatty acid compounds. The first fatty acid compound is selected from the group consisting of a linoleic acid compound, a linolenic acid compound, derivatives thereof and combinations thereof. The second fatty acid compound is selected from the group consisting of a docosahexaenoic acid compound, an omega-3 fatty acid compound, an omega-2 fatty acid compound, derivatives thereof and combinations thereof. Moreover, when the first fatty acid compound is linolenic acid or a derivative thereof and the second fatty acid compound is an omega-3 fatty acid, said omega-3 fatty acid is not linolenic acid or a derivative thereof. It is also preferred that when the first fatty acid compound is linoleic acid or a derivative thereof and the second fatty acid compound is an omega-2 fatty acid, said omega-2 fatty acid is not linoleic acid or a derivative thereof.

The two fatty acid compounds are present in the composition in critical proportions to one another. Preferably, the weight ratio of the first fatty acid to the second fatty acid is about 1:0.001 to 50. More preferably, the weight ratio of the first fatty acid compound to the second fatty acid compound is about 1:0.i to 10. Even more preferably, the weight ratio of the first fatty acid compound to the second fatty acid compound is about 1:0.9 to 2.5. Most preferably, the weight ratio of the first fatty acid compound to the second fatty acid compound is about 1:1 to 2.

The fatty acids of the present inventive subject matter may be used as such or as biologically acceptable and physiologically equivalent derivatives as, for example, detailed later herein. Reference to any of the fatty acids including reference in the claims is to be taken as including reference to the acids when in the form of such derivatives. Equivalence is demonstrated by entry into the biosynthetic pathways of the body as evidenced by effects corresponding to those of the acids themselves or their natural glyceride esters. Thus, indirect identification of useful derivatives is by their having the valuable effect in the body of the fatty acid itself, but conversion, for example, of gamma-linolenic acid to dihomo-gamma-linolenic acid and on to arachidonic acid can be shown directly by gas chromatographic analysis of concentrations in blood, body fat, or other tissue by standard techniques, well known to persons of ordinary skill in the art to which the present inventive subject matter pertains.

Derivatives of linoleic acid, as used in the present inventive subject matter, include, without limitation, salts of linoleic acid, alkaline salts of linoleic acid, esters of linoleic acid, and combinations thereof. Derivatives of linolenic acid, as used in the present inventive subject matter, include, without limitation, salts of linolenic acid, alkaline salts of linolenic acid, esters of linoleic acid, and combinations thereof. The salts and alkaline salts herein refer to those regularly used organic or inorganic salts which are acceptable for pharmaceutical use. Non-limiting exemplary linolenic acids include gamma-linoleic acid and dihomo-gamma-linolenic acid.

The fatty acids of the present inventive subject matter may be from any source, including, without limitation, natural or synthetic oils, fats, waxes or combinations thereof. Moreover, the fatty acids herein may be derived, without limitation, from non-hydrogenated oils, partially hydrogenated oils, fully hydrogenated oils or combinations thereof. Non-limiting exemplary sources of fatty acids include seed oil, fish or marine oil, canola oil, vegetable oil, safflower oil, sunflower oil, nasturtium seed oil, mustard seed oil, olive oil, sesame oil, soybean oil corn oil, peanut oil, cottonseed oil, rice bran oil, babassu nut oil, palm oil low erucic rapeseed oil palm kernel oil, lupin oil coconut oil, flaxseed oil, evening primrose oil, jojoba, tallow, beef tallow, butter, chicken fat, lard, dairy butterfat, shea butter or combinations thereof.

The ability to obtain immediate release, extended release, pulse release, variable release, controlled release, timed release, sustained release, delayed release, long acting characteristics and combinations thereof is performed using well known procedures and techniques available to the ordinary artisan. Each of these specific techniques or procedures for obtaining the release characteristics does not constitute an inventive aspect of this inventive subject matter all of which procedures are well known to those of ordinary skill in the art. As used herein, a “controlled release form” means any form having at least one component formulated for controlled release. As used herein, “immediate release form” means any form having all its components formulated for immediate release.

Any biologically-acceptable dosage form, and combinations thereof, is contemplated by the inventive subject matter. Examples of such dosage forms include, without limitation, chewable tablets, quick dissolve tablets, effervescent tablets, reconstitutable powders, elixirs, liquids, solutions, suspensions, emulsions, tablets, multi-layer tablets, bi-layer tablets, capsules, soft gelatin capsules, hard gelatin capsules, caplets, lozenges, chewable lozenges, beads, powders, granules, particles microparticles, dispersible granules, cachets douches, suppositories, creams, topicals, inhalants aerosol inhalants, patches, particle inhalants implants, depot implants, ingestibles, injectables infusions, health bars, confections, animal feeds cereals, cereal coatings, foods, nutritive foods functional foods and combinations thereof.

Any biologically-acceptable dosage form and combinations thereof are contemplated by the inventive subject matter. Examples of such dosage forms include, without limitation, chewable[[.]] tablets, quick dissolve tablets, effervescent tablets, reconstitutable powders, elixirs, liquids, solutions, suspensions, emulsions, tablets, multi-layer tablets, bi-layer tablets, capsules, soft gelatin capsules, hard gelatin capsules, caplets, lozenges, chewable lozenges, beads, powders, granules, particles Microparticles, dispersible granules, cachets, douches, suppositories, creams, topical, inhalants aerosol inhalants, patches, particle inhalants implants, depot implants, ingestibles, injectables infusions, health bars, confections, animal feeds cereals, cereal coatings, foods, nutritive foods functional foods and combinations thereof. The preparation of the above dosage forms are well known to persons of ordinary skill in the art.

Quick dissolve tablets may be prepared, for example, without limitation, by mixing the formulation with agents such as sugars and cellulose derivatives, which promote dissolution or disintegration of the resultant tablet after oral administration, usually within 30 seconds.

Cereal coatings may be prepared, for example, without limitation, by passing the cereal formulation, after it has been formed into pellets, flakes, or other geometric shapes, under a precision spray coating device to deposit a film of active ingredients, plus excipients onto the surface of the formed elements. The units thus treated are then dried to form a cereal coating.

For example, nutrition or health bars may be prepared, without limitation, by mixing the formulation plus excipients (e.g., binders, fillers, flavors, colors, etc.) to a plastic mass consistency. The mass is then either extended or molded to form “candy bar” shapes that are then dried or allowed to solidify to form the final product.

Soft gel or soft gelatin capsules may be prepared, for example, without limitation, by dispersing the formulation in an appropriate vehicle (vegetable oils are commonly used) to form a high viscosity mixture. This mixture is then encapsulated with a gelatin based film using technology and machinery known to those in the soft gel industry. The industrial units so formed are then dried to constant weight.

Chewable tablets, for example, without limitation, may be prepared by mixing the formulations with excipients designed to form a relatively soft, flavored, tablet dosage form that is intended to be chewed rather than swallowed. Conventional tablet machinery and procedures, that is both direct compression and granulation, i.e., or slugging, before compression, can be utilized. Those individuals involved in pharmaceutical solid dosage form production are well versed in the processes and the machinery used as the chewable, dosage form is a very common dosage form in the pharmaceutical industry.

Film coated tablets, for example, without limitation, may be prepared by coating tablets using techniques such as rotating pan coating methods or air suspension methods to deposit a contiguous film layer on a tablet. This procedure is often done to improve the aesthetic appearance of tablets, but may also be done to improve the swallowing of tablets, or to mask an obnoxious odor or taste, or to improve to usual properties of an unsightly uncoated tablet.

Compressed tablets, for example, without limitation, may be prepared by mixing the formulation with excipients intended to add binding qualities to disintegration qualities. The mixture is either directly compressed or granulated then compressed using methods or machinery quite well known to those in the industry. The resultant compressed tablet dosage units are then packaged according to market need, i.e., unit dose, roils, bulk bottles, blister packs, etc.

The present inventive subject matter contemplates nutritional compositions formulated for administration by any route, including without limitation, oral, buccal, sublingual, rectal, parenteral, topical, inhalational, injectable and transdermal. The physicochemical properties of nutritional compositions, their formulations, and the routes of administration are important in absorption. Absorption refers to the process of nutritional composition movement from the site of administration toward the systemic circulation. Most orally administered nutritional compositions are in the form of tablets or capsules primarily for convenience, economy, stability, and patient acceptance. They must disintegrate and dissolve before absorption can occur. Using the present inventive subject matter with any of the above routes of administration or dosage forms is performed using well known procedures and techniques available to the ordinary skilled artisan.

The present inventive subject matter contemplates the use of biologically-acceptable carriers which may be prepared from a wide range of materials, without being limited thereto, such materials include diluents, binders and adhesives, lubricants, plasticizers, disintegrants, colorants, bulking substances, flavorings, sweeteners and miscellaneous materials such as buffers and adsorbents in order to prepare a particular medicated composition.

Binders may be selected from a wide range of materials such as hydroxypropylmethylcellulose, ethylcellulose, or other suitable cellulose derivatives, povidone, acrylic and methacrylic acid co-polymers, pharmaceutical glaze, gums, milk derivatives, such as whey, starches, and derivatives, as well as other conventional binders well known to persons skilled in the art. Exemplary non-limiting solvents are water, ethanol, isopropyl alcohol, methylene chloride or mixtures and combinations thereof. Exemplary non-limiting bulking substances include sugar, lactose, gelatin, starch, and silicon dioxide.

The plasticizers used in the dissolution modifying system are preferably previously dissolved in an organic solvent and added in solution form. Preferred plasticizers may be selected from the group consisting of diethyl phthalate, diethyl sebacate, triethyl citrate, cronotic acid, propylene glycol, butyl phthalate, dibutyl sebacate, caster oil and mixtures thereof, without limitation. As is evident, the plasticizers may be hydrophobic as well as hydrophilic in nature. Water-insoluble hydrophobic substances, such as diethyl phthalate, diethyl sebacate and caster oil are used to delay the release of water-soluble vitamins, such as vitamin B6 and vitamin C. In contrast, hydrophilic plasticizers are used when water-insoluble vitamins are employed which aid in dissolving the encapsulated film, making channels in the surface, which aid in nutritional composition release.

The composition of the present inventive subject matter may be administered in a partial, i.e., fractional dose, one or more times during a 24 hour period, a single dose during a 24 hour period of time, a double dose during a 24 hour period of time, or more than a double dose during a 24 hour period of time. Fractional, double or other multiple doses may be taken simultaneously or at different times during the 24 hour period.

The compositions of the present invention are intended for use by humans and other mammals. The dosages are adjusted according to body weight and thus may be set forth herein on a per body weight basis. For example, if the formula specifies a range of about 10-1000 mg for a 55 kg individual, that range would be adjusted for a 35 kg individual to about 6.3-63 mg (e.g., the lower range limit=(35 kg/55 kg)*10 mg=6.3 mg). Decimal amounts may be rounded to the nearest whole number. In the above manner the present compositions may thus be adapted to be suitable for any individual, including any mammal, regardless of its size.

The present methods and compositions are adapted to meet the specific physiological needs of a woman planning to conceive a woman, who is pregnant, either with a single or multiple pregnancy, and/or a breast-feeding mother. For example, the formulations may focus on special nutritional needs of the mother that are not generally addressed in prenatal supplements, such as essential fatty acids, iron and calcium, without limitation. The iron and calcium, when present, are provided in amounts to optimize nutritional benefit to the mother, while minimizing unpleasant side effects which may accompany overly large doses. The formulation can be further tailored based upon the specific needs, genetic predispositions or identified deficiencies of women. Moreover, the present composition can be used as one component of a prescribed therapy.

The methods include administration of the present composition to women during a critical period. The critical period of administration is the period commencing at least at about the tenth week of pregnancy and terminating at the conclusion of breast-feeding or continuing on as a nutritional supplement for the mother. The methods include administering the compositions as early as three months prior to conception.

The present compositions and methods may increase lactogenesis or the quantity of breast milk produced during lactation. Further, the compositions and methods may prevent or at least minimize fatty acid deficiency in lactating women. The quality of breast milk may also be improved by the compositions and methods. Moreover, the duration of the period of lactation may be extended by the present compositions and methods. Thus, women who would have difficulty breast-feeding for more than four weeks after pregnancy when not taking the present composition, could breast-feed for more than four weeks after pregnancy when taking the present composition.

The foregoing is considered as illustrative only of the principles of the inventive subject matter. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the inventive subject matter to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the inventive subject matter.

Example 5

A soft gelatin supplement may be prepared, by first combining mineral oil and soybean oil in a first vessel and blending it to form a uniform oil mixture, heating the oil mixture to 45 degrees Celsius, and then adding propylene glycol. In a second vessel preheated to 70 degrees Celsius, yellow beeswax and soybean oil are added and blended until a uniform wax mixture is formed. The wax mixture is cooled to 35 degrees Celsius and then added to the oil mixture. To this combined oil and wax mixture, folic acid, vitamin B6, iron, magnesium, and calcium are then added and blended together to form a uniform biologically active mixture. The mixture is then cooled to 30 degrees Celsius to form a viscous biologically active core composition, after which time the composition is ready for encapsulation in a soft gelatin shell.

A soft gelatin shell is prepared by heating purified water in a suitable vessel and then adding gelatin. This water gelatin mixture is mixed until the gelatin is fully dissolved, and then glycerin, preservatives, one or more flavors, and one or more colorants are added. This gelatin mixture is blended well and cooled. The shells are then filled with the core composition and formed in accordance with soft gelatin techniques commonly used and well known to persons of skill in the art.
